This test panel includes most tests needed to more deeply explore the possibility of hypothyroidism and/or Hashimoto's disease diagnosis. It includes: TSH, Free T3, Free T4, Reverse T3, Thyroglobulin Antibody and Thyroid Peroxidase Antibody (Anti-TPO). If you are taking biotin, please stop it 72 hours before the blood draw since it may interfere with hormone blood tests. A study found that TSH was suppressed in all subjects after food, so fasting may be suggested although it is not reqired by Quest. Free T4 and Free T4 values did not change significantly after eating. NOTE: Reverse T3 is analyzed using a specific technique called liquid chromatography/tandem mass spectrometry (LC/MS-MS). There's a special place in the U.S. where these precise machines needed for LC/MS panels run only on two specific days a week. So, sometimes the clock ticks a bit while we wait for samples to return from their initial collection points. Results may take 7 business days.

Discounted Labs’ basic adrenal insufficiency panel includes cortisol, ACTH, and DHEA as a starting point. Depending on lab test results from this panel, physicians may choose to do an ACTH stimulation test, renin, potassium, and sodium. Imaging studies like a CT scan of the adrenal glands may also be considered to check for adrenal growths. In order to check for Addison's Disease, the auto-immune type of primary adrenal insufficiency, labs should be drawn to check 21-hydroxylase 

This PCT after cycle panel is designed to measure the health and recovery of the Hypothalamic-Pituitary-Testicular Axis (HPTA) after attempting to normalize it spontaneously or with the use of Post-Cycle Therapy (PCT) . PCT is prescribed by some physicians for men who stop testosterone replacement therapy (TRT) or other androgens. Fasting is required for CMP (glucose test).
